SPECIFICATION forming part of Letters Patent No. 479,311, dated July 19, 1892.

Application filed March 2, 1892, Serial No. 423,520. (No model.)

To all whom it may concern: The forward ends of the plates A B tern1i Be it known that I, JAMES R.

The device is then applied so that the radial slot of its twisting-wheel shall engage the aforesaid wire stringers, the crosspieces a; m shall rest against the face of the pickets, and the gage-block enter between the latter. The lever during this time being in its upper position is now pressed downward as far as it will go, after which it is moved backward until its sliding plates or catches shall engage the lower indentations of the frame- .plates, which brings the slot of the twistingwheel in line'with the open part of the frame, and thus permits of the removal of the device to secure in like manner the next picket.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a picket-wiring machine, the combination, with a suitable frame, of a gearwheel having a radial slot and side journals, as described, a segmental rack adapted to engage the gear-wheel, and a lever connected with the rack for operating the same, substantially as set forth.

2. In a picket-wiring machine, the combination of a frame composed of two triangular plates having perforated inner projections and securing-bolts, as described, the forward part of the frame having a slotted bearing and a radially-slotted gear-wheel journaled therein, an operating-lever with segmental rack pivoted in the rear part of the frame, indentures at the rear of the frame-plates, and the spring-actuated catches of the operating-lever, substantially as described.

3. The combination, in apicket-wiring machine, of a triangular frame having a slotted bearing and a radiallyslotted gear wheel journaled therein, an operating -lever with segmental rack pivoted in the rear of the frame, a pair of bearing-plates atthe forward part of the frame, and a gage-block secured to one of the bearing-plates, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
